BOW-FACING OAR.

SPECIFICATION forming part of Letters Patent No. 591,992, dated October 19, 1897,

Application filed February 13,189'7. Serial No. 623,328. (No model.)

To all whom t may concern:

Be it known that I, ANDREW P. SUNDBERG, a citizen of the United States, residing at Union I-Iill, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Rowlocks and Oars for Boats, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to rowlocks for boats, and the object thereof is to provide an improved device of this class whereby the oars may be connected with the boat and operated as hereinafter described, a further object being to provide improved oars and improved means for connecting the same with a-vboat, the devices for connecting the oars with the boat being so constructed that the oars may be swiveled or feathered as desired, and the oars being composed of separate sections and capable of longitudinal adjustment; and with these and other objects in view the invention consists of the construction,combination, and arrangement of parts hereinafter described and claimed.

. The invention is fully disclosed in the following speciiication, of which the accon`1'y panying drawings form a part, in which-,

Figure 1 is a transverse section of a part of one side of a boat, showing nay-improvement and the application thereof; Fig. 2, a

plan view of the oar and the means forconnecting the same with the boat; Fig. 3, a sec-V tion on the line 3 3 of Fig. 1; Fig. 4, a section on the line 4,4 of Fig. 2, Figs. 3 and 4 being on an enlarged scale; Fig. 5, a section on the line 5 5 of Fig. 4, and Fig. 6 a section on the line 6 6 of Fig. 1.

In the drawings forming part of this speciflcation, the separate parts of my improvement are designated by the same numerals of reference throughout the several views, and in Fig. 1 I have shown at 5 a section of one side of a boat, and in the practice of my invention I provide a rowlock 'and an improved oar which are of theffollowing construction, and adapted to be connected with the boat in the following manner:

Secured to the side of the boat are two'upright standards 6, each of which is provided with a tubular head 7, and these tubular heads 7 are adapted to receive tenons or projections 8, which are formed on or mounted in cylindrical heads 9, which are provided with outwardly-directed arms 10, the outer ends of which are connected by a cross-bar 11 on which is mounted a cross-head 12. The cross-head 12 is provided centrally with a hub 13, through which the cross-bar 1l passes, and at each side of said hub is a collar i 14, which is formed on or secured to the cross-v bar 11, and by means of Which the cross-head 12 is held centrally of said bar, and the inner end of said cross-head 12 is provided with a vertical bore 15, in which is mounted a rev-- oluble cylinder 16, which is revoluble in said cross-head, and said cylinder 16 is provided below the cross-head with an annular collar 17and above said y cross-head is a plate v13, which is secured thereto by a bolt or lscrew 19.

The cylinder 16 is free to revolve in the cross-head 12, and is provided with two downwardly-directed circular jaws 20, between which is pivoted a similar jaw 21, which is provided with a downwardly-directed shank 22, whichv is provided with a sleeve 23, in which is formed a transverse slot 24, and mounted in the outer end of the cross-head 12, and revoluble therein, is a standard 25,

the lower end of which is provided with a sleeve 26,- in which is formed a transverse slot 27, similar to that formed in the sleeve 23.

'The upper end of the standard 25 is provided with a plate `23, which is held in place by a screw or'bolt 29, and formed on said standard, below the said cross-head 12, is a collar 30, and said standard is free to revolve in said cross-head, and is held therein by the plate 23.

The oar which I employ is preferably coinposed `o'f four separate sections 31, 32, 33, and 34, and the section 31 projects inwardly and is provided with a handle 35, whilethe section 34 is provided with the usual blade 36. The section 31 is provided with artubular easing 37, which passes through the sleeve 23-on the shaft-22,y which is provided with the jaw 2 l, which is pivoted between the jaws 2O of the cylinder 16, and a set-screw 38 is passed through the. slot 24 in said sleeve, and throughv the tubular casing 37, and the said IOO tubular casing is provided near ils outer end and in the upper surface thereof with a slot 3f).

The section 32 of the oar is connected with the section 3l by a coupling-head 40, which is provided at its inner end with a metal casing 41, which enters the outer end of the tubular casing 37 of the section 3l of the oar, and a set-screw42 is passed through the slot 39 in the tubular casing 37, and through the tubular casing 4l into the coupling-head 40, and as thus constructed the coupling-head 40 is free to slide within certain limits in the tubular casing 37. The coupling-head 40 is connected with the inner end of the section 32 of the oar, as shown in Figs. 3 and 4, by a hinged joint or coupling 44, and the section 33 is connected with the section by a coupling-head 45, and said coupling-head is connected with said section 32 by a hinged joint or coupling 4G, and the joints or couplings at 44 and 46, and that by which the cylinder 1G is connected with the sleeve 23, or the shank .'2 thereof, are all of the same con struct-ion, but the last-named coupling or joint and the joint 44 are in avertical plane, while the coupling or joint 46 is in a horizontal plane, when the parts are in the position Shown in Figs. 1 and 2.

The inner end of the section of the oar is provided with a metal easing 47, on which is mounted a tubular sleeve 43, into which the coupling-head 45 passes, and in which it is secured, and the tubular sleeve 43 passes through the sleeve 26 ot' the standard 25, and is free to move therein, and formed in the upper side of the sleeve 48 is a longitudinal slot 49, and passing through the sleeve 2G, and through the slot 49 in the tubular sleeve 4S, and through the tubular casing 47 of the section 33 of the oar is a set-screw 50.

The outer end of the section 33 of the oar is provided with a tubular casing 51, which is adapted to receive the inner end of the section 34, which is also preferably provided with a tubular easing 52, and formed in the upper side of the casing 51 is a longitudinal slot 53, through which is passed a set-screw 54, which passes through the tubular casing 52 and into the section 34. As thus constructed, it will be seen that the section 34 is adjustable in the outer end of the section 33, and that the section 33 is adjustable in the tubular casing 4S, by which it is connected with the coupling-head 45, and the coupling-head 40, by means of which the section 32 is connected with the inner section of the oar, is also adjustable in the tubular casing 37 of the said section 3l. It will also be seen that the inner end of the inner section may be raised or lowered on the hinge or coupling by which it is connected with the cylinder 16, and that the outer end of the section 3l is adapted to swing in a horizontal plane by means of its connection with the section 32, and that the outer end of the section 32 and the inner end of the section 33 are adapted to move in a vertical plane by reason of the understood from the foregoing description y when taken in connection with the accompanying drawings and the following statement thereof.

It will be understood that both sides of the boat are provided with a rowlock and oar similar to that herein described, and by means of my improved rowlock and the oar constructed as described, the paddle 3G may be feathered in the usual manner, and the oar operated as usual in this class of devices. The length of the various sections and the couplings by which they are connected are also such as to give great leverage to the inner section 31, and by means thereof the boat may be propelled at a greater speed with a less applieation of power than in ordinary devices of this class.

It will be apparent that changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, l claim as new and desire to secure by Letters Patent 1.
